Butterfly Valve
J-VALVES
Structural Features
Nickel-Aluminum Bronze Material: Both the valve body and disc are made of ASTM B148 C95800 nickel-aluminum bronze, which offers excellent corrosion resistance and high strength, and is especially suitable for seawater and chemical media.
Lug-Type Connection: Adopts a lug-type connection, ensuring convenient installation and reliable sealing, and facilitating maintenance and replacement.
Double Eccentric Design: The unique double eccentric design reduces friction between the disc and the valve seat, improving sealing performance and service life.
Replaceable Seal: The sealing material is replaceable, with reliable sealing performance to achieve zero leakage, ensuring the long-term effective operation of the valve.
Valve Stem Sealing: The valve stem adopts a multi-layer sealing design, which is not easy to deform, avoiding the common problem of valve stem leakage and ensuring operational safety.
Automatic Centering Function: The disc is equipped with an automatic centering function, realizing a slight interference fit between the disc and the valve seat to further enhance sealing performance.
Multiple Operation Modes: Offers multiple operation modes including handwheel, gear, pneumatic actuator, and electric actuator, meeting the needs of different working conditions.
